문서 용어 행렬을 생성 할 때 속성 오류가 발생합니다.

Question

팬텀 데이터 프레임의 형식으로 표현 된 문서 용어 행렬을 생성하려고합니다. 여기 내 코드는 지금까지 있습니다 :

df_profession['Athlete_Clean'] = df_profession['Athlete Biographies'].str.lower() 
df_profession['Athlete_Clean'] = df_profession['Athlete_Clean'].apply(lambda x: ''.join([i for i in x if not i.isdigit()])) 
df_profession['Athlete_Clean'] = df_profession['Athlete_Clean'].str.split() 
df_profession['Athlete_Clean'] = [word for word in df_profession['Athlete_Clean'] if word not in punctuation] 
df_profession['Athlete_Clean'] = [word for word in df_profession['Athlete_Clean'] if word not in stopwords.words('english')] 

profession_dtm_athlete = pandas.DataFrame(countvec.fit_transform(df_profession['Athlete_Clean']).toarray(), columns=countvec.get_feature_names(), index = df.index) 
profession_dtm_athlete 

나는 다음과 같은 오류가이 코드를 실행하면 :

'list' object has no attribute 'lower' 

나는이 오류를 제거 할 수 있습니까

?

Answer 1

랩 목록은 문자열로 변환하는 STR()에서 객체 :

df_profession['Athlete_Clean'] = str(df_profession['Athlete Biographies']).lower() 
df_profession['Athlete_Clean'] = df_profession['Athlete_Clean'].apply(lambda x: ''.join([i for i in x if not i.isdigit()])) 
df_profession['Athlete_Clean'] = str(df_profession['Athlete_Clean']).split() 
df_profession['Athlete_Clean'] = [word for word in df_profession['Athlete_Clean'] if word not in punctuation] 
df_profession['Athlete_Clean'] = [word for word in df_profession['Athlete_Clean'] if word not in stopwords.words('english')] 

profession_dtm_athlete = pandas.DataFrame(countvec.fit_transform(df_profession['Athlete_Clean']).toarray(), columns=countvec.get_feature_names(), index = df.index) 
profession_dtm_athlete
